SEPARABLE BUTTON.

SPECIFICATION forming part of Letters Patent No. 745,089, dated November24, 1903. Application led February 6.1903. Serial No. 142,149. (Nomodel.)

To @ZZ whom, it ncrty concern:

Be it known that I, CLIFTON YEoMANs, a citizen of the United States, anda resident of the city of New York, borough of Manhattan,in the countyand State of New York, have invented a new and Improved SeparableButton, of which the following is a full, clear, and exact description.Y

My invention relates to an improvement in that class of buttonsconsisting of a socket and a knob section,`the knob-section beingadapted Vfor locking engagement with the socket-section.

The purpose of the invention is to provide a simple, durable, andeconomic separable button capable of being readily, firmly, andexpeditiously applied, and, furthermore, to so construct the button thatthe more one section is forcibly drawn from the other section the morefirmly will the two sections remain in locking engagement, and also toso construct the socket-section that a cap member will have limited playupon the body portion, it being necessary to move the cap member outwardupon the body portion before the two sections of the button can beseparated'.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a vertical section through the socket portion of the button,a side elevation ot the knob portion in locking engagement with thesocket-section, and a section through the material to which the partsare secured. Fig. 2 is a View similar to that shown in Fig. 1, exceptthat the two parts of the button are separated; and Fig. 3 is asectionthrough the socket portion of the button, showing a slight departure inthe construction of the said part.

`The invention relates particularly to the socket-section A of thebutton, which socketsection is used in connection with a knobsection Bbut the latter section B may be of any approved type.

In the construction of the socket-section A, as is disclosed in Figs. 1and 2, a cup-body 10 is provided which is of metal and of a rigid of theaforesaid inner annular projection.

11, and at the upper end of the cup-body 10 a smalleroutwardly-extending horizontal flange 13 is produced. The material 14,to which the socket-section A is to be secu red, is providedwithasuitable openingto receive the body 10, and the bottom iange l2 ofthe said section engages with the under face of the said material. Atthe upper face of the material a washer 15 is made to engage, whichwasher is circular and extends around the aforesaid body 10. This washer15 is angular in crosssection, comprising a horizontal base member and avertical member. The vertical member is in engagement with the outerface of the body 10, and the upper flange 13 of the said body is made tofirmly engage with the upper edge of the vertical portion of the saidangular washer 15, as is shown in both Figs. 1 and 2. 1n this manner thesaid body 10 is securely fastened to the material 14.

An inner expansible cup member Gis iitted in the outer cup-body member10 in such manner that the inner expansible cup member C will have moreor less play to and from the outer stationary body member 10. This innerexpansible cup member Ois constructed of a spring material, and its sideportions incline more or less downwardly and inwardly from the top,being decidedly inwardly curved at the bottom portion 17, as is shown inFigs. 1 and 2, and when the socket-section A is locked to theknob-section B this lower curved portion 17 of the inner expansible cupmember O is in engagement with the inner annular projection 11a at thebottom port-ion of the outer xed cup-body member 10, so that theknob-section when fitted in the socket-section will serve to hold thepart 17 against the said inner annular projection of the body-sectionthe more firmly the more an endeavor is IOO made to separate the twosections by simply drawing one section from the other. At the bottom ofthe inner expansible cup member C an opening 18 is produced, and at thetop of the said inner expansible cup member C an outwardly-extendingflange 19 is formed, which is preferably given a downward and outwardinclination, and the body portion of the said inner expansible cupmember C is provided with a series of slots 20, produced therein,permitting the said body portion of the said inner expansible cup memberto expand and contract as maybe necessary for the entrance or withdrawalof the knob-section B. A cap-plate 21 crowns the said socketsection A.This cap member 21 is more or less semicircular, having its outersurface conveXed and its inner surface concaved, and the said cap member21 is provided with an inwardly-directed flange 22 at its marginextending beneath the under surface of the body of the said member atits marginal portion,

lwhich conforms to the inclination of the flange 19 at the upper portionof the inner expansible cup member C, a central vertical shank, and alower horizontal member,which rests upon the horizontal member of thewasher 15,which engages with the material 14.

A space is normally provided between the lower horizontal mein ber ofthe washer or ring 23 and the horizontal member of the clamping washeror ring 15 *when the socket-section A is in its normal position, as isshown in Fig. 2, and when the knob-section is in locking connection withthe said socket-section the lower horizontal member of the ring orwasher 23, connected directly with the cap member 21, will rest upon thehorizontal portion of the fixed washer 15, so that a space is thenprovided between the lower horizontal .member of the washer 23 and theunder face of the flange 13 at the top of the fixed body member 10 ofthe socket, and before the knobsection can be released from thesleeve-section the cap member 2l must be raised to bring the outerwasher 23, connected with the cap, in engagement with the upper flange13 of the body-cup member 10, as is shown in Fig.v 2, so that by suchaction the lower decidedly-curved portion of the said inner eX- pansiblecap member will be carried from engagement with the aforesaid innerannular projection 11l at the bottom of the body-clip member 10, as isalso shown in Fig. 2, and

only at such time can a separation between the two sections A and B takeplace.

The cap-section B consists of a segmental head 24 and a shank 25, whichis in two diameters, thus forming a circular shoulder 26. The shank 25is passed through a suitable opening in the material 29, to which theknobleaving the socket-section A.

section B is to be attached, a washer 28 having previously been placedon the shank 25 in engagement with the shoulder 26, so as t0 engage withthe upper face of the said material 29, and-a second and lower washer 27is then made to engage with the under face of the material 29, beingsecured to the bottom or inner end of the shank 25 in any suitable orapproved manner.

In the operation of this separable button the knob-section B can bereadily and quickly forced up into the inner expansible cup member C ofthe socket-section A, as during such act the knob-section will force theexpansible cup member C upward, and the heady 24 of the knob-section canthen readily enter the said expansible cup member. After such connectionthe knob-section B will naturally settle down and will draw the innerexpansible cup mem ber C downward,so that its conveXed surface 17 willrest against the said inner annular projection 1ll at the bottom portionof the body member 10.

It will thus be observed that when an attempt is made to forciblyseparate the fabric or other material connected by the two sectionsdescribed such attempt will cause the head 24 of the knob-section B toforce the outer convexed portion 17 of the inner or eX- pansible cupmember C so tightly against the projection 11iL of the body member 10 asto effectually prevent the said inner cup member C from expanding, andconsequently prevent the head 24 of the knob-section B from fect aseparation between these two sections,

it is necessary to first raise the cap member 21, bringing the parts tothe position shown in Fig. 2, and thus carrying the bottom portion ofthe inner expansible cup member C from engagement with the bottomportion of the body member 10, whereupon as the knobsection is drawnaway from the socket-section the inner member C of the latter will befree to expand and permit the head 24 to leave it.

In Fig. 3 I have illustrated a slightly-modilied form of thesocket-section A, in which the only dierence consists in that thefixingwasher 15 is dispensed with and two substantially Z-shaped washers30 and 31 are employed instead, the washer 3l corresponding to thewasher 23, attached to the cap 21 and shown in Figs. 1 and 2. The innerZ-shaped washer 30 under this latter construction has its lowerhorizontal member held firmly against the material 14 by theoutwardly-extending upper flange 13 of the body 10, while the outerZ-shaped ange of washer 3l, being attached to the cap 21, is free tomove upward and downward with the said cap, .the movement of the capbeing limited by the lower member of the outer Z-shaped washer 3lstriking the outer member of the inner Z- shaped washer 30 on thematerial to which the socket is secured.
